A certain product uses two $32\mathrm{.}768$KHz crystals, one of which is used by the WiFi module. However, the customer wants to use just one crystal to meet the design requirements of the current two crystals. The R$8$D team has received the task to reduce costs while meeting the original customer specifications. They decided to use DOE $($Design of Experiments$)$ to study the key factors affecting WiFi TX throughput and RX throughput so that the reduced number of crystals still melet customerspecifications $($TX throughput $=30$ Mbps$,$ RX throughput $>30$ Mbps$).$ The $|$team decided to study three factors: A $($CL$),$ B $($Cs$),$ and C $($CLK Level$),$ each with $2$ levels, using a $23$ full factorial design with $2$ replicates at each corner point. The experimental results are shown in Minitab file "WiFi Throughput"$\text{'},$ where TX represents TX throughput and RX represents RXthroughput. Answer the following questions:a$.$ To maximize TX throughput and RX throughput, what should be the settings for factors A $($CL$),$ B $($Cs$),$ and C $($CLK Level$)?(8$ pts$)..($Hint: Choose one from each: A$.$ o$\mathrm{.}0$ or $12\mathrm{.}0$ bho or dC: $1\mathrm{.}8$ or $3\mathrm{.}3)$b$.$ Based on the settings for A$,$ B$,$ and C from part $($a$),$ what is the $95\%$ prediction interval for TX throughput? $(7$ ptst
